Custom piezoceramic rings for vibration transducer and custom vibration transducer


Ultrasound vibration cutting has so many advantages that it can be widely used in cutting difficult-to-machine materials in aviation, aerospace, military and other fields.

1. Cutting of difficult-to-machine materials: heat-resistant steel, titanium alloy, constant elastic alloy, superalloy, stainless steel, chilled cast iron, engineering ceramics, composite materials and granite, etc.

2. Processing hardened steel parts and superhard parts can obtain high processing accuracy and surface quality: Hardened steel parts with hardness of HRC60 or above can be easily processed with carbide tools, such as high-speed steel, bearing steel, etc. Processing carbide with PCD tools can greatly improve the tool durability.

3. Forming Cutting: Using Forming Cutting Tools to Machine Various Types of Contour Surfaces, Internal and External Spherical Surfaces, Over-arcs, Conical Surfaces, etc.

4. Turning of slender rods and thin-walled parts

5. Turning of Ultra-fine Diameter Parts

6. Ultra-precision Machining



Applications: High power ultrasonic vibration transducer
